York said the department has notified all police chiefs in the county, saying everyone should be on high alert.

"It hits close to home," York said. "We have also notified the FBI. We take this very seriously."

The hit list was discovered at a time of increased tensions across the country between police and many of the communities they serve. In July, videos captured law-enforcement officers fatally shooting black men in Louisiana and Minnesota, and law-enforcement officers were ambushed by gunmen in Dallas, Baton Rouge, Louisiana, and San Diego.

According to an Ottawa County sheriff's report, the hit list was found behind the Clay Township garage and shows six stick figures with X's through them, with Clay Township Police written next to the stick figures.

The department has 16 police officers.

The names of four area residents also are on the list, which details how many shots each one would receive and the caliber of handgun to be used.

The list also include five first names, each with hash marks beside them, but it is not known to whom the names refer, according to the sheriff's office report.

The report also states that Genoa and Lake Township are on the hit list, but it does not specify if those targets are law enforcement-related.

Beneath the listed names is a shopping list for 20 smoke cans, ammunition and one stick of dynamite, according to the report.

The note also states "Graytown Park Twp. Monday, 9:00," but does specify 9 p.m. or 9 a.m.

Clay Township, which has a population of about 5,000, is in western Ottawa County on the Wood County border. The village of Genoa is in the center of the township.
